class bpy.types.FModifier(bpy_struct)

Modifier for values of F-Curve

active

F-Curve modifier will show settings in the editor

Type: boolean, default False

blend_in

Number of frames from start frame for influence to take effect

Type: float in [-inf, inf], default 0.0

blend_out

Number of frames from end frame for influence to fade out

Type: float in [-inf, inf], default 0.0

frame_end

Frame that modifier’s influence ends (if Restrict Frame Range is in use)

Type: float in [-inf, inf], default 0.0

frame_start

Frame that modifier’s influence starts (if Restrict Frame Range is in use)

Type: float in [-inf, inf], default 0.0

influence

Amount of influence F-Curve Modifier will have when not fading in/out

Type: float in [0, 1], default 1.0

is_valid

F-Curve Modifier has invalid settings and will not be evaluated

Type: boolean, default False, (readonly)

mute

Enable F-Curve modifier evaluation

Type: boolean, default False

show_expanded

F-Curve Modifier’s panel is expanded in UI

Type: boolean, default False

type

F-Curve Modifier Type

NULL Invalid.
GENERATOR Generator – Generate a curve using a factorized or expanded polynomial.
FNGENERATOR Built-In Function – Generate a curve using standard math functions such as sin and cos.
ENVELOPE Envelope – Reshape F-Curve values, e.g. change amplitude of movements.
CYCLES Cycles – Cyclic extend/repeat keyframe sequence.
NOISE Noise – Add pseudo-random noise on top of F-Curves.
LIMITS Limits – Restrict maximum and minimum values of F-Curve.
STEPPED Stepped Interpolation – Snap values to nearest grid step, e.g. for a stop-motion look.

Type: enum in [‘NULL’, ‘GENERATOR’, ‘FNGENERATOR’, ‘ENVELOPE’, ‘CYCLES’, ‘NOISE’, ‘LIMITS’, ‘STEPPED’], default ‘NULL’, (readonly)

use_influence

F-Curve Modifier’s effects will be tempered by a default factor

Type: boolean, default False

use_restricted_range

F-Curve Modifier is only applied for the specified frame range to help mask off effects in order to chain them

Type: boolean, default False

classmethod bl_rna_get_subclass(id, default=None)

Parameters: id (string) – The RNA type identifier.
Returns: The RNA type or default when not found.
Return type: bpy.types.Struct subclass

classmethod bl_rna_get_subclass_py(id, default=None)

Parameters: id (string) – The RNA type identifier.
Returns: The class or default when not found.
Return type: type
